Examples of com.google.gwt.xml.client.Element

com.google.gwt.xml.client.Element
This interface represents XML DOM elements, which are the basic building block of XML. An example follows:
```
  Some text more text  
```

    NodeList nodeList = this.document.getChildNodes();


    for (int i = 0; i < nodeList.getLength(); i++) {
      Node n = nodeList.item(i);
      if (n.getNodeType() == Node.ELEMENT_NODE) {
        Element root = (Element) n;
        return root;
      }
    }


    throw new XmlException("Can't find any Root Element");
